android에서 웹 서비스를 사용하는 중 예외적 인 오류가 발생했습니다.

Question

지금 SOAP 서비스를 사용하여 Android 서비스에서 웹 서비스를 사용하고 있습니다.

edittext에서 입력을 받아 적절한 값을 표시해야합니다. 즉, 웹 서비스를 호출하고 결과를 반환해야합니다.

에뮬레이터가 실행 된 후 "ERROR : java.lang.RuntimeException : 0004"을 직렬화 할 수 없습니다.이 오류는 어떻게 처리됩니까? 여기

은 찾을하시기 바랍니다 내 코드입니다

screen.java

public class X_classActivity extends Activity 
{ 
    private EditText edit; 
    private Button btn; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     edit = (EditText) findViewById(R.id.editText1); 
     btn = (Button)findViewById(R.id.button1); 
     btn.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
         fun(); 
      } 
     }); 
    } 

private void fun() 
{ 
    //getSOAPResponse() method returns SOAP Response 
    SoapObject soapResponseObject = getSOAPResponse(edit.getText()); 
} 

public SoapObject getSOAPResponse(GetChars search) 
{ 
    SoapObject soapObject = new SoapObject("http://tempuri.org/", "GetName"); 
    soapObject.addProperty("str", search); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12); 
    envelope.dotNet = true; 
    envelope.setOutputSoapObject(soapObject); 
    HttpTransportSE androidHttpTransport = new  HttpTransportSE("http://122.248.240.105:234/Service1.asmx?WSDL"); 
    try 
    { 
     androidHttpTransport.call("http://tempuri.org/GetName", envelope);//call the eb service Method 
     Object result = envelope.getResponse(); 
     System.out.println(" " + result.toString()); 
     ((TextView) findViewById (R.id.textView2)).setText(""+result.toString()); 
    } 
    catch (Exception E) 
    { 
     E.printStackTrace(); 
     ((TextView) findViewById (R.id.textView2)).setText("ERROR:" + E.getClass().getName() + ":" + E.getMessage()); 
    } 
    return soapObject; 
    } 
}

나는 당신이 라인에 뭔가를 잘못하고있는 생각은,

androidHttpTransport.call("http://tempuri.org/GetName", envelope);//call the eb service Method 

나는 첫 번째 인수가 잘못 생각합니다. 다음 코드를 참조하십시오, 그것은 나를 위해 잘 작동합니다. 또한 프로젝트를 빌드 할 때 사용하는 종속성을 내보내십시오. 때때로 그것은 당신을 도울 것입니다.

private String METHOD_NAME = ""; 
    // our webservice method name 
    private String NAMESPACE = "http://ws.travel_ceylon.web.org"; 
    // Here package name in webservice with reverse order. 
    private String SOAP_ACTION = NAMESPACE + METHOD_NAME; 
    // NAMESPACE + method name 
    private static final String URL = "http://192.168.177.130:8080/Travel_Ceylon_Central_Web_Service/services/Travel_Ceylon_Web_Service?wsdl"; 

    // you must use ipaddress here, don’t use Hostname or localhost 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     String city = "Matara"; 
     String im = "Galle Face"; 

     METHOD_NAME = "getLongitude_City"; 
     try { 
      SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
      request.addProperty("city", city); 
      SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11); 
      envelope.dotNet = true; 
      envelope.setOutputSoapObject(request); 
      HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
      androidHttpTransport.call(SOAP_ACTION, envelope); 
      Object result = envelope.getResponse(); 
      ((TextView) findViewById(R.id.txtCityLongitude)).setText(city 
        + " Longitude is : " + result.toString()); 

     } catch (Exception E) { 
      E.printStackTrace(); 
      ((TextView) findViewById(R.id.txtCityLongitude)).setText("ERROR:" 
        + E.getClass().getName() + ":" + E.getMessage()); 
     }
